Successful Medical Management of Severe Neonatal Cushing Syndrome with Metyrapone, Guided by Mass Spectrometry Monitoring

Poidvin Amelie , Storey Caroline , Martinerie Laetitia , Braun Karine , Lahlou Najiba , Leger Juliane , Carel Jean-Claude

Background: Neonatal Cushing syndrome is a rare and severe condition, mostly associated with the McCune-Albright (MCA) syndrome. Management options include medical treatment (with ketoconazole or metyrapone resulting in 11-beta-hydroxylase blockade) and radical treatment with bilateral adrenalectomy. Spontaneous regression in late infancy has been reported.Objective and hypotheses: To report on the outcome of a 14 month-old girl with severe neonatal Cush...

Pituitary Function after Mild to Severe Traumatic Brain Injury in Children 2–18-Years-Old: A Prospective Study

Braun Karine , Briet Claire , Toussaint Patrick , Trifunovic Helene Bony , Boudailliez Bernard

Background: In recent years, traumatic brain injury (TBI) has been identified as a significant cause of pituitary dysfunction in children. Paediatric prospective studies are rare especially for mild TBI.Objective and hypotheses: The aim of this present study was to evaluate the frequency of hypopituitarism after mild, moderate and severe TBI in hospitalized children, and determining factors of this deficiency.Method: A prospective ...

Think Histiocytosis X Facing Insipidus Diabetes with Thickened Pituitary Stalk

Lichtenberger-Geslin Lydia , Gourmel Antoine , Sainte-Rose Christian , Trifunovic-Bony Helene , Braun Karine , Boudailliez Bernard , Devoldere Catherine

Background: Insipidus diabetes is a rare disease in pediatric endocrinology.Objective and hypotheses: Facing a thickened pituitary stalk on MRI pituitary, the main diagnosis to mention are: dysgerminoma, histiocytosis, sarcoidosis, and autoimmune hypophysitis. Histiocytosis is a rare and often underdiagnosed cause.Method: We report the case of a teenage girl who presented polyuria–polydipsia syndrome at the age of 14 years con...

Stem Cells in the Pituitary: A Role for Regeneration?

Rizzoti Karine

During morphogenesis, embryonic progenitors proliferate, differentiate and establish the shape of the future organs and tissues. In the mature organism, a certain degree of plasticity and potential for regeneration is retained as most organs maintain a population of adult stem cells sharing important similarities with embryonic progenitors; they are characterized by the ability to both self-renew and differentiate into the full range of the specialized cell types corresponding...

Sleep and Glycaemic Control in Children with Type 1 Diabetes

Spiegel Karine

Rapidly accumulating epidemiologic and experimental evidence has indicated that insufficient sleep, such as commonly experienced in modern societies by all age groups, reduces insulin sensitivity and impairs glucose metabolism in healthy adults, and increases the risk of incident type 2 diabetes. Studies in type 1 or type 2 diabetic adults show a link between reduced sleep quality or duration and poor glyceamic control. While poor diabetes control may impair sleep due to noctu...

Deterioration in polysomnographic evaluation after COVID-19 infection in patients with Prader-Willi-Syndrome

Braun Sina , Schulte Sandra , Laemmer Constanze , Gohlke Bettina

Background: Patients with Prader-Willi-Syndrome (PWS) seem to be a risk-group for COVID-19 infection, due to their syndrome associated clinical features of hyperphagia and obesity, risk for central hypoventilation and obstructive sleep apnoea. Yet, little is known about the severity of infections and the long-term consequences in these patients. Therefore, we studied auxologic parameters and sleep laboratory examinations in PWS patients before and after COVID-...

Phenylbutyrate treatment of three patients with Monocarboxylate Transporter 8 deficiency

Zung Amnon , Schreiner Felix , Vollbach Heike , Schweizer Ulrich , Banne Ehud , Braun Doreen

Background: Monocarboxylate transporter 8 (MCT8) deficiency is a rare genetic disease that leads to severe global developmental delay. Thyroid hormone (TH) profile is characterized by high T3 and low T4 levels, with normal or elevated TSH. Recent studies have shown that the chemical chaperone phenylbutyrate (PB) restored mutant MCT8 function and increased TH content in a patient-derived cell model, making it a potential treatment for MCT8 deficiency.<p cla...

Clinical Follow-up of the First SF-1 Deficient Female Patient

Gerster Karine , Biason-Lauber Anna , Schoenle Eugen J

Background: Steroidogenic factor 1 (SF-1/NR5A1) plays a crucial role in regulating adrenal development, gonad determination and differentiation, and in the hypothalamic-pituitary control of reproduction and metabolism. In men (46, XY) mutations in SF-1/NR5A1 gene cause a wide phenotypic spectrum that ranges from complete testicular dysgenesis with Müllerian structures and amenorrhea, through individuals with mild clitoromegaly or genital ambiguity, to severe penoscrotal h...

Unexplained Altered States of Consciousness in a Girl

Graf Stefanie , Gerster Karine , Kroiss Sabine , Konrad Daniel , Schonle Eugen

Background: In children, congenital hyperinsulinism is the most common cause for endogenous hyperinsulinaemic hypoglycaemia (HH). Beyond infancy other diagnoses may be considered, such as insulinoma, an insulin-secreting neuroendocrine tumour (NET) arising mostly from the pancreas. The latter is a rare cause of HH in children. The estimated incidence of insulinoma is 1:250Â’000 person-years of all age groups with a median age at diagnosis of 47 years. Herein, we report an ...

Contrasting Central Diabetes Insipidus due to preproAVP Mutations: Earlier Onset of Symptoms in Recessive than in Dominant Forms

Bourdet Karine , Valette Sophie , Deladoey Johnny , Vliet Guy Van

Background: Central diabetes insipidus may result from mutations in the preproAVP gene, most often heterozygous and occurring de novo or inherited in an autosomal dominant mode; in these cases, intracellular accumulation of the misfolded product of the mutated allele slowly destroys the AVP-producing neurons, so that the onset of symptoms may be delayed for up to 28 years by which time the posterior pituitary hyperintense signal is no longer visible on magnetic resonance imagi...
